Genome Scan For Chromosomal Microarray Analysis Blood
What is this test?
Genome Scan for Chromosomal Microassay Analysis Blood test is a medical genetic test, that helps to find out the blood diseases or conditions that are caused due to mutations in the genes of an individual.
What Chromosomal Microarray Analysis:
Chromosomal microassay CMA is a type of chromosomal test which can detect extra (duplication of chromosomes) and missing (deletion) chromosome material in the patients who are having genetic disorders or diseases. This test can not detect the chromosomes that switch spots and are upside down.
CMA can detect more than 150 genetic conditions that are caused by chromosome deletions and duplications.
Why this test is performed:
This test is performed to check if an individual is having any genetic mutations that can cause blood diseases or not. This test may be recommended to you by a physician if you or your family members have any inherited diseases, low iron levels, blood cancer, increased clotting time, delay in wound healing, very low levels of red blood cells etc.
This test also helps the doctors to plan the treatment according to the type of gene that gets mutated and the condition that affects the individual. In some cases, this test is also performed to check the effectiveness of the treatment.
Also known as Genome Scan for Chromosomal Microarray Analysis.
Test Preparation
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your Genome Scan For Chromosomal Microarray Analysis Blood. Your doctor will give specific instructions depending on your condition on how to prepare for Genome Scan For Chromosomal Microarray Analysis Blood.
No specific preparation is necessary for this test.
Understanding your test results
Your test results may be true negative or uninformative negative.
True negative means that the specific gene mutation is a reason for the medical conditions that are related to the blood diseases in your family and it didn’t inherit to you.
Uninformative negative means that the gene mutation is not identified in the family previously but there is a chance for a mutation in the gene that was tested.
If your test results are positive, then it may indicate there is a chance for a mutation in the genes that cause the blood diseases like blood cancer, very low blood levels etc.
If abnormal test results were seen, consult your doctor or a genetic counselor immediately with your test reports.
